by KarlosJ83, Gear Expert from UT, United States Updated on August 29, 2014
Since its mid August I'm unable to field test this bag. From my examination, the materials seem to be first class and the workmanship is very good. Looking forward to using it when cold weather arrives.

I bought this bag in order to save weight and keep warm on the Colorado Trail this coming summer. I have always used Marmot down bags. The reason I decided to go with Big Agnes this time is that I have always been unhappy with the way down bags don't insulate very well under the body because the down gets compressed when you lay on it.

Got it 2 weeks before my trip to the Wilderness. I was very impressed with the room when zipped fully up. I was able to turn over since I do not sleep in the same position and can't stand to be completely confined. Was plenty warm enough since it got down into low 40's and 30's. With a light long sleeve T-shirt, again, I like to sleep with my arms free as well, it did very well...
